Is there a suitable substitute for 2N3904 transistor?

Is there a suitable substitute for 2N3904 transistor?

Your circuit is only powered with 9V, and the current passing through each transistor is limited to less than 20mA, so any replacement that can handle eg. 20V and 100mA will be fine. Next is Electrical Characteristics. Depending on the application, some may be more important than others.

Which is better 2N3904 or 2N2222?

Compared to the 2N3904 the 2N2222 is a larger (higher capacitance and maximum currents, lower saturation voltage at high currents), slower, considerably lower noise device. Re: Why use 2N3904 vs 2N2222?

What is the gain value of a 2n4401 transistor?

2N4401 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin. 2N4401 has a gain value h fe of 500; this value determines the amplification capacity of the transistor.

Which is better the 3904 or the 4401?

The 3904 is better at really low currents, but the 4401 can handle higher currents. Most of the time the 4401 is good enough, so I “standardized” on it since it’s more robust and I run into 100 mA applications more than 100 µA applications. Once you pick something as your jellybean part, you want to use it whenever it’s good enough.

Can a transistor be used for a dark light sensor?

Dark/Light sensor using transistor. Automatic dark detector senses darkness. As the light level decreases and LDR meets the maximum threshold resistance, the circuit automatically switches on the LED D1.

Are there equivalent transistors with the opposite pinout?

Some equivalent transistors have the opposite pinout (E,B,C) and some are B,C,E. This won’t be a problem so long as you are aware of the difference, and refer to the datasheet of the part you are using when wiring up the circuit.

Which is better the 2n9013 or the 3904?

It looks from the datasheet that the 2n9013 has twice the Ic (continuous collector current) of 500mA, compared to a peak in the 3904 of 200mA. The 3904 is definitely intended to be a signal amplifier, and has a gain bandwidth product of 300MHz.

Which is the PNP complementary of 2N3904?

PNP Complementary of 2N3904 is 2N3906 . Replacement and Equivalent: 2N2222, S8050, 2N4401, BC537, SS9013 (Pin configuration of some transistors may different from 2N3904 therefore check pin configuration before replacing in a circuit) 2N3904 Transistor Explained / Description: 2N3904 is a widely used general purpose transistor.

Can a 3904 be used as an amplifier?

The 3904 is definitely intended to be a signal amplifier, and has a gain bandwidth product of 300MHz. The 9013 datasheet I found doesnt even have GBP, which to me tells me its much more intended as a current buffer, than as an amplifier.
